This innovative history of supermarkets describes the role of food and agriculture during and after the Cold War. American business leaders and political figures deployed American supermarkets around the world as explicitly anticommunist "weapons" in the Cold War economic contest with the Soviet Union. Modern supermarkets, built upon industrial agriculture supply chains, penetrated world political and economic spheres during the Cold War Farms Race, embodying a pervasive rhetoric of exceptional American food abundance, a counterrevolutionary ideology of capitalist economic development, and a moral claim to the justifiability of U.S. economic power on the world stage. The farmers who produced the food for supermarket supply chains were enlisted in the Farms Race in ways that shaped how agricultural development schemes proceeded in the latter half of the twentieth century. Ultimately, notions of U.S. food power were reconfigured into global systems of market power coordinated by multinational agribusiness corporations. The stage was set for our present moment, in which transnational supermarkets operate as powerful institutions of nonstate governance in the global food economy.
